本文以吴旗油田吴93井区油藏为例,在吴93井区沉积微相、储层综合分析评价的基础上,选取有效厚度、渗透率、孔隙度、含油饱和度、渗流系数、储能系数、流动层指数和油藏品质指数等八个参数进行流动单元的划分。将长6油藏划分为A,B,C和D四类流动单元。划分结果表明,吴93井区长611和612是该区长6油藏的主力油层,各类流动单元与储层岩性、物性和沉积微相具有很好的对应关系。本次流动单元划分的参数取值,综合评价函数与评价指标,可以客观地反映低渗、低孔、储层物性差、非均质性强等地质特征。
Based on the analysis of the sedimentary microfacies and reservoirs in Well Wu 93 and the reservoir of Well Wu 93 in Wuqi Oilfield, this paper chooses effective thickness, permeability, porosity, oil saturation, seepage coefficient, Energy coefficient, flow index and reservoir quality index eight parameters such as flow unit division. The Chang 6 reservoir is divided into four types A, B, C and D flow units. The result of division shows that the area 611 and 612 of the well W101 are the main reservoirs of reservoir Chang 6 reservoirs, and all kinds of flow units have good correspondence with reservoir lithology, physical properties and sedimentary microfacies. The parameters of the flow cell division, comprehensive evaluation function and evaluation index can objectively reflect the geological characteristics such as low permeability, low porosity, poor reservoir physical properties and strong heterogeneity.
